The presenttinvention relates to improvei ments infeedingbottles` for. infants Vand particularly to an arrangement; for fixing teatsito, feeding bottles-4 andghas yfor. `its object to provide agsecureand. durable| ,fixation of the teat so that the latter cannot he pulledrolfrthegbottle by a tension exerted on the teat. Arrangements of this type are already known; a constructional example of such arrangements comprises a screw threaded sleeve which is screwed over the teats fitted to the neck of the bottle, the latter being provided with screw thread. This arrangement presents the disadvantage that the teatV is injured and torn when the sleeve is screwed on it. Another constructional eX- ample comprises a springy ring the ends of which overlap each other and which may be fixed to the neck of the bottle by pressing the two ends towards each other. This ring is disadvantageous inasmuch as it does not tightly press the teat against the neck of the bottle so that liquid from the. feeding bottle may escape.

Further it is known to use an elastic rubber ring as a ymember for holding the teat. This form shows the drawback that after a short use the rubber ring loses its elasticity as it is tensioned and is soon rendered unfit for use. The metal rings provided with locking means which have also been used and which contact directly with the teat cause a quick wear of the latter.

These drawbacks are overcome by the arrangement according to the present invention which shows the feature that a circular ring consisting of a rigid material is used having a U-shaped cross-section open towards its inner side, an elastic insertion being arranged inside the U-shape and intended for pressing the teat against the neck l of the bottle.

A construction example of the subject matter of the present invention is illustrated on the accompanying drawings, in which Fig. l shows the upper part of the neck of a feeding bottle with the means for holdinga teat illustrated in section,

fclampingringf. The latter ,is of a: U- `shaped Across-section opemtowarclsl the interior and consists preferably of a metal.` In the hollow space thus formed an elastic insertion 4 is arranged whichmay consist of rubber or of a similar material. In order to increase the elasticity the insertion ring 4 is provided with recesses 5.

The teat or mouth piece 7 is pulled through the clamping ring 3, then the latter is pulled over the neck 1 of the-bottle 1 until the clamping ring 3 enters the groove 2. Owing to the elastic insertion 4 the teat is tightly pressed against the neck of the bottle and an escape of liquid from the bottle is not possible.

To facilitate the clamping ring 3 together with the teat 7 to be placed on the-neck of the bottle the latter is provided with a conical enlargement 8 which joins to the groove 2 and the portion 9 of the neck on the other side of the groove is of a larger diameter than the enlargement 8.

The clamping ring 3 may readily be removed by pulling the ring sideways in several directions and sliding it thereby over the neck. Y

The circumferential groove 2 in the neck 1 of the bottle 1 may also be omitted as is shown in Fig. 5 in which case the clamping ring is held in position below the enlargement 8. The end part 10 of the neck is shown to? taper slightly inwardly towards the enlargement 8. y

I claim: 9

1. yAn arrangement for fixing teats to feeding bottles for infants, comprising a circular ring of a rigid material and having aU- shaped kcross-section, the open part ofthe cross-section pointing towards the inner side 100 of thering, and an elasticy ring inserted in said U-s'haped cross-section of the ringand adapted to causea pressure on the neck of the bottle when pushed over the latter.

. 2. An arrangement for rfixing kteats to 105 feeding bottles for infants, comprising a circular ring ofa rigid material and having a U-shaped cross-section, the open part of the cross-section pointing towards the inner side of the ring, and an elastic rubber ring vki11- 1N serted in said Ushaped cross-section of the ring and adapted to cause a pressure on the neck of the bottle when pushed over the latter.

3. An arrangement for fixing teats t0 feeding bottles for infants, comprising a circular metallic ring of a U-shaped cross-section, the open part of the cross-section pointing towards the inner side of the rin and an elastic rubber ring inserted in sai U-shaped cross-section of the metallic ring, said rubber ring being provided with recesses for increasing its elastic forces with which it presses towards the neck of the bottle when it is pushed over it.

4. A feeding bottle for infants, comprising in combination, a neck theend part of which flares slightly inwardly towards an enlargement of said neck, a rubber tea-t, and a clamping ring for securing said teat to the neck below said enlargement, said clamping ring consisting of acircular metallic ring of n a. U-shaped cross-section, the open part of the cross-section pointing towards the inner side of the ring, and an elastic rubber ring inserted in said U-shaped cross-section of the metallic ring, said rubber ring being provided with recesses for increasing lits elastic forces with which it presses the teat in said groove of the bottle.

In testimony whereof, I have signed my name to this specification.
